The Tolsen 16128 is a flexible head breaker bar designed for loosening and tightening nuts and bolts in confined spaces where a standard straight tool cannot reach. This 460 mm long tool features a 1/2" drive and a hinged joint head that pivots up to 180°, allowing you to adjust the angle of force to suit the specific layout of your workspace. Built for industrial use, it is crafted from hardened and tempered chrome vanadium steel with a polished chrome plating that helps prevent corrosion. The handle includes a knurled surface to ensure your hand stays secure during heavy use, while a spring-loaded ball bearing keeps the socket firmly in place during operation.
